GARBID-FEEDER FOR ACETYLENE-GENERATORS.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed May 6, 1907. Serial No. 371,982.

To all whom it may concern:

Be it known that I, ISAAC PEInoE, a citizen of the United States, residing at Tazewell, in the county of Tazewell and State of Virginia, have invented new and useful Improvements in Carbid-Feeders for Acetylene-Generators, of which the following is a'specification.

This invention relates to a feeding device for acetylene generators, and relates more particularly to a swinging container or holder for the carbid mounted in the gasometer and operated directly by the vertical movement thereof, as in the case of a combined generator and gasometer, or which is located in the generator chamber and operated through a suitable mechanism controlled by the movement of the gasometer bell, as in that type of apparatus in which the generator is separate from the gasometer.

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, thoroughly reliable and eflicient in use, and capable of being readily adjusted for regulating the feed of the carbid to the water in the generator.

A further object of the invention is the provision of a carbid feeding device which is mounted for oscillation within the generator of the apparatus and adapted to be automatic in its operations, the movement of the gasometer being depended upon for oscillating the feeder to periodically discharge the requisite amount of carbid to maintain a continuous generation of gas.

Another object of the invention is the provision of a suitable container having an inclined bottom or chute, with an adjustable deflector over the discharge end of the chute, and an adjustable pan or suitably shaped member that receives a charge from the chute while the container or holder is in one position, and empties said charge into the Water while in another extreme position.

A still further object is the employment of a hopper arranged above the open end of the carbi container or holder and provided with a flexible spout controlled from outside the apparatus for conveniently re-charging the holder from time to time, without requiring the latter to be removed.

With these objects in view, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illus trates one of the embodiments of the inventionz Figure 1 is a vertical section of the carbid feeding device. Fig. 2 is a side elevation of a bottom portion thereof. Fig. 3 is a front elevation of a separate generator and gasometer set equipped with the improved carbid feeder. Fig. 4 is a sectional view of the upper portion of a generator and the carbid feeding device.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, 1 designates a metal container or holder for carbid of parallelopiped or any other suitable form, and preferably open at its to The bottom of the hol der is provided with an opening 3 of triangular shape under which is arranged an inclined scoop-like chute 4 through which the charges of carbid are delivered. Arranged within the holder 1, at a point above the edge of the chute 4, is a de ector plate or valve 5 hinged at 6 and resting on the inner end of an adjusting screw 7. This screw extends through a threaded opening 8 in the wall of the holder 1 and can be turned to adjust the position of the deflector late so as to regulate the flow of carbid from the chute.

Arranged under the chute is a scoopshaped member or an 9 that is hinged at its closed end to the ower edge of the holder adjacent the discharge end of the chute, the hinge being indicated at 10.

. The member 9 may be adjusted to vary its inclination, by means of a slotted strip 11 depending from the bottom of the holderl and a screw or bolt on the member 9 extending through the slot of the strip there being a clamping nut 12 on the screw.

The holder 1 is adapted to be mounted within the generator of the acetylene generating apparatus and is fulcrumed or journaled on a horizontal shaft 13.

When the carbid feeding device is used in connection'with a combined generator and gasometer, the holder is provided with an upwardly-extending arm 14 that carries on its extremity an anti-friction roller 15 which is adapted to engage the under surface of the bell 16 of the gasometer and ride along the said surface, as the bell moves up and down with. the variations in the volumes of the acetylene gas.

In practice, the holder is filled with carbid and as long as the bell is fully raised or su ported by the gas, the holder will assume t e full line position shown in Fig. 1. When Eh e bell falls to its lowermost position, as the gas is consumed, the feeding device will be tilted, as shown by dotted lines. ing, a charge of carbid will be deposited from the pan 9 into the water of the generator and gas will be created. This causes the bell to gradually rise and permit the feeding device to automatically return by gravityto the full line position. While turning from the dotted to the full line position, a charge of carbid will pass from the chute 4 into the pan 9 and will be retained in the latter until the device is again tilted by the lowering of the bell by the consumption of the acetylene gas. The member 5 serves to regulate the amount of material supplied for each charge and co operates with the chute for preventing material from being delivered continuously into the water when the device is in the dotted line position. By adjusting the pan or member 9, the osition at which the device will deposit a c arge into the water can be regulated to a nicety.

Referring to Fig. 3, which illustrates a sep arate generator and gasometer set, 17 repre sents agenerator and 18 the gasometer of any approved construction and which are connected by a gas pipe 19, in the usual manner.

In the u per portion of the generator body is the oscillating carbid holder 20, mounted on a horizontal shaft 21 journaled at its ends in the walls of the generator body. One end of the shaft 21 is formed into a crank 22, located outside of the generator and connected with a lever 23 by a slot connection designated by 24. The lever 23 is fulcrumed on a bracket 25 and has one end disposed in the path of a projecting member 26 on the bell 27 of the gasometer so that as the gasometer falls to its lowermost position the lever 23 will be actuated and thereby swing the carbid holder 20. The projecting member 26 for actuating the lever is one of a pair of apertured ears on the bell 27 that engage vertical guide rods 28 for guiding the movement of the bell.

construction as the one heretofore described and operates in a similar manner. As long as the bell 27 contains as the parts on the carbid feeding device wilIbe in a full line position and as soon as the gas is consumed the bell operates through the lever 23 to throw the carbid holder to the dotted line position whereupon a charge of carbid is dropped into the water. The resulting gas causes the bell 27 to rise and the member 26, disengages from the lever so that the parts of the feeding In the act of til The carbid holder is of the'same device can return to normal position by gravity and be in readiness to deposit another charge of carbid when again tilted to the dotted line position.

The carbid holder is preferably permanently mounted in the generator and in order to refill the holder from time to time, a hopper 29 is supported on the top of the generator and has a neck 30, extending into the generator. Attached to this neck is a flexible spout 31 to which is hingedly connected an actuating rod 32 passing through the top of the generator. The hopper is normally closed by means of a cap or cover 29 which prevents the escape of gas to the atmosphere. 30 This rod is held in adjusted position by a spring dog 33. When the spout is in the full line position the flow of carbid from the hopper 29 to the holder 20 is effectively cut off but when the spout is shifted to the dotted 5 line position by means of the actuating rod 82, the carbid will flow into the holder to recharge the same. The hopper, which is' preferably gas tight, can be conveniently suplied any time so as to be in readiness to re- '1ll the holder when desired. Communicating with the bottom of the generator are two pipes 34 and 35 controlled'by valves, one pipe serving as a drain and the other for supplying water to flush out the generator. Thus, by opening the valves of the pipes a circulation through the generator can be produced so that the sediment can be effectively washed out.

From the foregoing description, taken in this connection with the accompanying drawing, the advantages of the construction and of the method of o eration will be readily apparent to those skil ed in the art to which t e invention appertains, and while I have described the principle of operation of the invention, togetherwith the apparatus, which I now consider to be the best embodiment thereof, I desire to have it understood that such changes may be made as are Within the 11 scoIpe of the invention.
